An evolution is impossible, whose process inescapably needs simultaneous changes of genes that creates the body character and that creates the nerve center capable of controlling it. A mere change of the body character means nothing without the controlling function of the nerve center. For example, wings without the nerve center controlling them do not work. It's like a situation that you have a printer without its controlling device. The average number of base pairs of a human gene is 7000. The number of type of bases is 4 (A, G, T and C). The probability of accidental alignment of the bases so that they can create the nerve center able to control the body character is 1 / 4 ^ 7000, which is almost equal to zero.
